Created attachment 279235 [details] 4.19.0 kernel dmesg errors when waking up after monitor blanking
The mainline kernel 4.19.0 from kernel.org works, but after blanking the monitor for 4 hours and waking up there is familiar amdgpu errors in dmesg. However the system works fine.
I commented out all dmesg errors and now my non debug kernel is silent when waking up from monitor blanking. Please put all development traces under DEBUG_KERNEL symbol.
